SF6 Air Sensor testing for Hitachi

SF6 Air Sensor testing for Hitachi

With tracer gas method, test parts remain dry, and measurement are unaffected by temperature changes and elasticity. The actual gas mix is a safe combination of 5% Hydrogen and 95% Nitrogen. Hydrogen is the lightest and least hazardous of all gases, it spreads rapidly throughout the test part and seeps quickly through the
